[0035] It is found through research that the prior art has the following disadvantages: when the rotor core of the motor is disassembled, the knocking method is a common disassembly method, and it is difficult to find the force point during disassembly.

[0036] Based on the above research, the utility model discloses a force point is added to the bottom of the rotor core, and the pressing rod is used to press instead of knocking to solve the problem.
[0037] The defects of the above-mentioned solutions are the results of the inventors after practice and careful research, therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to solve the above-mentioned problems should be the contribution of the inventors to the present disclosure in the process of the present disclosure.
[0038] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0039] Some embodiments of the utility model will be described in detail below in combination with the drawings. In the case of no conflict, the embodiments and features in the embodiments described below can be combined with each other.
[0040] Referring to Figure 1 The rotor core dismounting tool provided by the embodiment of the present disclosure comprises a support sleeve 100 sleeved outside an inner sleeve 200, and the length of the inner sleeve 200 is less than the length of the support sleeve 100, so that a gap is left between the bottom of the inner sleeve 200 and the bottom of the support sleeve 100.
[0041] Further, the inner sleeve 200 is provided with a swelling sleeve 210, and the bottom of the inner sleeve 200 is inwardly protruding and provided with a blocking ring 240 adapted to abut against the swelling sleeve 210 to prevent it from falling off. A through hole 211 is formed in the middle of the swelling sleeve 210, and a pressing head 220 is further arranged above the swelling sleeve 210, the pressing head 220 being connected to one end of a pressing rod 230, and the other end of the pressing rod 230 being connected to a driving device as a force applying end.
[0042] Specifically, the inner sleeve 200 is adapted to place a rotor assembly, and the rotating shaft of the rotor assembly is adapted to pass through the through hole 211, so that the swelling sleeve 210 is used as a fulcrum to clamp the rotor core to prevent it from shaking, and the driving device drives the pressing rod 230 and the pressing head 220 to press down the rotating shaft, the rotating shaft is pressed to pass through the through hole 211 and falls into the gap between the bottom of the inner sleeve 200 and the bottom of the support sleeve 100, so that the rotating shaft and the rotor core are separated, thereby avoiding the deformation of the surface of the rotor core caused by knocking the rotating shaft.
[0043] Referring to Figure 2 In some embodiments, the swelling sleeve 210 comprises two half-round clamping rings 212 with an “L” cross section, the center of the half-round clamping ring 212 has a semicircular arc, and the two half-round clamping rings 212 form the through hole 211 after being combined. The swelling sleeve 210 is designed as a pair of half-round clamping rings 212, which is convenient for replacement and maintenance. When the rotor assembly of different models is targeted, the swelling sleeve 210 with corresponding inner diameter and through hole 211 can be replaced according to the size of the rotor assembly, thereby increasing the flexibility of the rotor core dismounting tool.
[0044] Continuing to refer to Figure 1 In some embodiments, the outer wall of the pressing head 220 is tangent to the inner wall of the swelling sleeve 210. Through the above arrangement, after the swelling sleeve 210 is replaced, the pressing head 220 is adapted to extrude the inner wall of the swelling sleeve 210, so that the two half-round clamping rings 212 move away, thereby making the outer wall of the swelling sleeve 210 abut against the inner sleeve 200.
[0045] Referring to Figure 3 In some embodiments, an end cover 300 is further arranged above the support sleeve 100, the end cover 300 is provided with a hole suitable for the pressing rod 230 to pass through, and the hole is adapted to fix the pressing rod 230 to prevent it from shaking during the pressing process of the pressing rod 230, thereby further increasing the stability of the rotor core dismounting tool.
[0046] In conclusion, the inner sleeve 200 of the rotor core dismounting tool is suitable for placing the rotor assembly, the rotating shaft of the rotor assembly passes through the through hole 211, the expansion sleeve 210 is suitable for clamping the rotor core to prevent it from shaking, the pressing rod 230 and the pressing head 220 press the rotating shaft, so that the rotating shaft is separated from the rotor core, thereby avoiding the deformation of the surface of the rotor core caused by knocking the rotating shaft.
[0047] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, and can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0048] In the description of the present application, it should be explained that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, terms such as "first", "second" and other numerical terms are used in this paper, unless otherwise indicated in this paper. Therefore, the above discussed first element, component, region, layer or section can be referred to as the second element, component, region, layer or section without departing from the teachings of the example embodiments.
[0049] Spatially relative terms, such as "inner", "outer", "below", "below", "lower", "above", "upper", and the like, can be used herein to facilitate description of the relationship of one element or feature to another element or feature as illustrated in the drawings. In addition to the orientation depicted in the drawings, the spatially relative terms can be intended to cover different orientations of the device in use or operation. For example, if the device in the drawing is turned over, the element described as "below" or "under" the other element or feature will be oriented "above" the other element or feature. Therefore, the example term "below" can cover the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0050] With the above ideal embodiment of the present application as the inspiration, through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and the technical scope must be determined according to the scope of claims.
